I sell a good number of antique/vintage switches which include Rotary, Snap, Push Button, Tap, Despard Style, Tumbler & Toggle. They come in single-pole, double-pole, 3-way, 4-way, High/Low/Medium & momentary switches. And some unusual switches as well. You can go to My Store to see what I currently have listed. I also have a backlog of switches I haven't listed yet, so if you need a particular type of switch (brand name, size, etc.) or quantity, please contact me and maybe I have what you need. 


⭐  Unique among vintage switch sellers, I thoroughly clean and test all my switches to ensure they are in proper working condition. If this is a restored switch then see last photo for a sample restoration.
